After a long night filled with smoking weed and hours of intense sex, one woman experienced the unexpected: She couldn’t stop having orgasms. For weeks, she continued to have orgasms that lasted for hours at a time, even when she wasn’t receiving any sexual stimulation from herself or her male partner.

The 40-year-old woman—who’s referred to as Mrs. A—is thought to represent the first known case of its kind, according to the report published inthe Journal of Sex and Marital Therapy. Mrs. A became increasingly worried about her symptoms after reading online about restless genital syndrome, a permanent condition that causes a similar experience with either restless legs or the feeling of an overactive bladder.

After about three weeks of experiencing spontaneous orgasms and developing severe anxiety, she sought professional medical help, the study's lead author, Dr. Marcel Waldinger, a neuropsychiatrist in private practice in the Netherlands, tells Newsweek via email.

To explain and document her problem, she filmed one of her episodes and showed it to Waldinger. Mrs. A didn’t present the characteristic symptoms of restless genital syndrome, such as having orgasms while sitting down, so Waldinger ruled that out.

She chose not to have sex anymore, but her orgasms still persisted even after only smoking marijuana.

"She still got spontaneous orgasms within one minute after smoking cannabis. When smoking a small amount of cannabis, the spontaneous orgasms were controllable, but after smoking a higher amount of cannabis, the spontaneous orgasms became completely uncontrollable," Waldinger says.

The doctors also looked for clinical symptoms of potential tumors near the clitoris, but they concluded none were present. Therefore, they decided the intense, five-hour sex session and cannabis use may have overactivated a nerve, making the orgasms uncontrollable.

Past research has linked marijuana and increased sexual feelings. “Edibles or smoking marijuana can definitely have a positive effect on sexual inhibition,” Ian Kerner, a sex and relationship specialist, told Men’s Health. “It can help people’s anxiety melt away and achieve orgasms they’ve never had before.”

But Waldinger believes his case report sheds new light on the topic. "It is known that cannabis may inhibit or facilitate sexual feelings. However, the current idea is that this is due to the anxiety-reducing properties of cannabis or to the idea that it increases the skin sensitivity for touch," he says. "The current case report is important, as the spontaneous orgasms may indicate that cannabis itself may have a direct pharmacological effect on orgasm." More research is needed, he notes.

As for Mrs. A, she still suffers from spontaneous orgasms. To avoid this, Waldinger recommended she stop smoking cannabis.

Senator Bob Menendez said he was "disappointed, but not surprised, that the Trump administration has failed once again to prioritize our long-term national security interests or stand up for human rights."
